Synda

Synda turns your Garmin into an open water swimming companion. Start a swim from your wrist and get live distance, heart rate, calories, and pace on the watch — even when your phone stays on shore. Every swim records full GPS so you can review the exact route afterwards. When you pair it with the Synda app on your phone, every swim syncs automatically. There you can discover thousands of wild swimming spots worldwide, log the conditions you swam in, and share the story behind every place you swim with the Synda community.
